*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Lake Bohinj (Bohinjsko jezero) is the largest natural lake in Slovenia, located in the heart of the Julian Alps. Despite its alpine setting, the water warms up pleasantly in summer. From June to September, the surface temperature usually ranges between 20–24°C, and during hot spells it can even rise to 25°C. In spring and autumn, however, the lake is much cooler, often between 10–15°C, while in winter it stays just a few degrees above freezing.
Because of these conditions, Bohinj is very popular for swimming and other water activities. There are several natural bathing areas along its shores, and the water is clear and inviting. Families, swimmers, and even kayakers find it a comfortable place during summer, though outside of the warm season only the more adventurous go in for a quick dip.
